New quantum computing architecture achieves record speed and accuracy in 2025
A research team from Sungkyunkwan University has introduced a groundbreaking quantum computing architecture. Called Shuttling-based Distributed Quantum Computing (SDQC), the system delivers faster speeds and fewer errors than existing methods. The team, led by Seunghyun Baek, Seok-Hyung Lee, Dongmoon Min, and Junki Kim, presented their findings in 2025 after successfully testing the approach on complex problems.
The SDQC architecture combines two key techniques: physically moving qubits and distributing quantum information across multiple processing units. This hybrid approach allows for all-to-all connectivity between qubits, enabling programmable quantum operations with dozens of qubits at once.
SDQC marks a significant step forward in distributed quantum computing. Its combination of speed, low error rates, and scalable design offers a practical solution for complex quantum problems. The architecture's success in real-world tests suggests potential for broader applications in quantum information processing.
